To all whom it ntay concern:

Be it known that I, RICHARD IV. HUDSON, a

. citizen of the United States,residing at Toledo,

in the county of Lucas and State of Ohio,have invented certain new and useful Improvements in Cash-Registers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has reference to a cash-register, and has for its object 'to provide a machine of this character the mechanism of which shall be extremely simple and compact in construction and effective in operation, comprising few working parts, consequently insuring low cost in manufacturing.

To reduce the cost of manufacture to a minimum, the parts constituting the mechanism of my invention are largely constructed of sheet metal punched out by means of suitable dies, insuring perfect interchangeability and convenience in assembling.

In carrying out my invention I provide simple, effective, and easily-operated mechanism for registering the amount of a sale and simple and positive mechanism for indicating the amount of a sale, the two mechanisms coacting to produce precise operation.

In the drawings, Figure l is a perspective View of the register, showing the case for confining the mechanism and the working parts extending through the case adapted for manual operation. Fig. 2 is a rear elevation of the operating mechanism. Fig. 3 is a sectional elevation showing the registering meeh` anism, the parts being located to the left of the section-line w w, Fig. 2. Fig. 4 is a sectional elevation showing the indicating mechanism, the same being located to the right of the section-line x 0c, Fig. 2. Fig. 5 is a rear elevation of the counter mechanism, the parts shown being located forward of the sectionline 1/ gj, Fig. 3. Fig. (5 is a left side elevation ot' one of the counter-wheels and the mechanism for rotating the same. Fig. 7 is a det-ail in perspective of one of the flanged rings of the counter-wheels, the same being detached. Fig. S is an enlarged elevation showing the operation of the transferring mechanism of the counter-wheels. Fig. 9 is a detail in elevation ot' the means for returning the indicator-cylinders to their normal positions. Fig. 10 is asectional detail showing the concentric arrangement of thc spindles fortransmitting motion to the indicatorcylinders. Fig. l1 is a similar view showing the concentric arrangement of the spindles upon which the indicator cylinders arc mounted.

In the various Afigures in which the case is shown the same is illustrated in section, as indicated by the section-lines.

Referring to the parts, l is a suitable case having the general outline shown in Fig. 1. The same is provided with a suitable cashdrawer 2, formed with a catch 3, adapted to engage the end of a key-lever Al, fulcrumed at 5, which extends through an opening in the case and is adapted to be depressed to the position shown in dotted lines a, Fig. et, by which means the drawer is released, the return of the key-lever tbeing accomplished by a coiled spring or other suitable means. The cash-drawer after being released bythe key-lever is forced outward by the action of a coiled spring G.

7 is a hinged closure for an opening through the case to permit examination of the numerals upon the counter-wheels. lClosure 7 is provided with a suitable lock and key, by reason of which unauthorized inspection of the total amount registered and indicated by the numerals upon the counter-wheels is insured against.

The fingers by which the machine is operated are shown at 8, Fig. l., and in the same figure 9 represents openings through the case to disclose the numerals upon the indicatorcylinders to indicate the amount of a cash purchase.

I will now describe the registering mechanism.

10, ll, and l2, respectively, are counterwheels suitably mounted to permit independent rotation. As shown, each comprise a disk 13, formed with peripheral teeth let, and a ring l5, formed with an inwardly-extending 'lange 16, provided with perforations 17, preferably at equidistant points to permit ot' fastening to the disk 13 by means of screws or rivets, coincident perforations 1S being provided in the disks 13 for this purpose. The counter-wheels are preferably three in number, as shown in Fig. 5, the left indicating y cents,the middle one tlimes,andtlieone to the rightdollars,. numerals being provided upon the rings to indicate the same. These numerals may be imprinted directly upon the rings 15 or the same may be stamped to present a raised appearance upon metal strips to be attached to the rings by soldering or otherwise. The ratchet-teeth 14E `upon the counter-wheels are in number a multiple oi' ten, and in the application of my invention as illustratedin the drawings l provide fifty teeth upon each counter-wheel. Closely adjoining each counter-wheel is a ratchet-arm 19, movable independent therefrom. The same are provided 'with gravity operated pawls 20 to engage the teeth 14 upon the counter-wheels and are extended beyond the periphery of the counter-wheels and secured at 2l to the arc-shaped operating-plates 22, having axes of curvature coincident with the axis ot the counter-wheels. Plates 22 extend through openings in the ease and are exposed and accessible from the forward side of the case. Extending radially from the operating-plates 22 are operating-fingers S,here inbefore mentioned. The fingers are arranged at equidistant points upon the plates 22, the angle between the same being equal to the angle ot' a single ratchet-tooth. The plate to the right, looking at the plates 22 from the forward side of the machine, is adapted for registering cents, and the same is preferably stamped or otherwise marked in proximity to the fingers 8, beginning with the lower finger and going upward with characters.01,.02,.03,.04t,.05, .06, .07,77 .08, and .00. In like manner the middle plate 22 is adapted for registering dimes, and the same is stamped, beginning the lower finger .10, .20, .30, .40, .50, .00, .70, .80, .90. The plate to the right is similarly stamped 1., 2., 3., 4., 5., 0., 7., 8., au( 9. and is adapted for registering dollars.

23 is a ledge formed on the case, provided with openings 2lto permit the Vlingers S to pass therethrough when the operating-plates 22 are forced downward. 'lhelowermost fingers upon the plates 22 normally occupy a position above the ledge 23 equal to the distance between the lingers.

25 represents antifriction-wheels to insure the easy operation of the operating-plates 22.

2G represents cylindrical band-wheels independently revoluble, each having one end of a flexible metallic band 27 secured to the periphery thereof, the opposite ends of said bands being attached at suitable points te the operating-plates 2S represents idle pulleys, over which the bands 27 are guided.

Band-wheels 26 are each provided with a band-spring 20, the inner end of which is secured to the hub portion of the band-wheel in the usual well-known manner. The outer terminals of said springs are secured to a transverse rod 30, being thereby held in a partly-wo und state. By this means the bands 27 are subjected to constant tension, and the operating-plates 22 are normally held in the position shown in Alfull lines, Fig. 3, the further upward movement oi' the same being prevented by forming a stop upon the plate, as at 31.

32 represents spring-operated pawls, coperating with the ratchet-teeth 1lto prevent backward movement of the counter-wheels.

The numerals upon the counter-wheels correspond in position to the ratchet-teeth upon said wheels, each numeral being placed opposite a ratchet-tooth. Upon the counter-wheels which register cents and dimes the space opposite every tenth tooth is left blank, there being five such blank spaces upon each of said wheels. The consecutive series of numerals 1, 2, 3, 1, 5, 0, 7, S, 0 and the blank space are therefore repeated live times upon the cents counterwheel, and the series 10, 20, 30, 40, 50, G0, 70, S0, 00 and the blank space five times upon the dimes counter-wheel. The counter-wheel registeringdoliars is numbered consecutively from 1 to 50, inclusive, one numeral bebeing arranged opposite each ratchet-tooth upon said wheel.

As every tenth space upon the cents and dimes counter-wheels is a blank, means are provided l'or transferring the cents to the dimes counter-wheel and the dimes to the dollars counter-wheel when the aggregate of cents or dimes registered on their respective wheels amounts to ten or more. The means for accomplishing this is shown in Figs. 25, 5, 0, and 8, Fig. S showing the operation of the parts in dotted lines. Arranged upon the cents and dimes counter-wheels at the peripheries thereof and opposite the blank spaces thereon are laterally-extending projections in the form ot pins 3-1- is an arm pivoted at 35 and normally held in the position in full lines, Fig. S, by a spring 30. lrojecting laterally from the arm is a stud normally in position in the path oi' rotation of the pins 33 and which when engaged by one of the pins 33 causes the arm Si; to assume the position in dotted lines l), Fig. S. Pivoted to arm 341 is a.gravity-pperated pawl 37, formed at its free end with a laterally-projecting triangular pin 38 to engage the ratchet-teeth 14;. The pawl 37 on the opposite side of its pivotal point is cnlarged, as at S0, to counterweight the same. The parts are arranged so that the motion of. one counter-wheel will. be transmitted to the next or higher counter-wheel to move the ITO same the distance of one ratchet-tooth, after which the arm 34 is released to take its normal position.

I also provide means for preventing an overthrow of the counter-wheels, the same cooperating with the transferring mechanism just described. Should the registering mechanism be operated quickly and with considerable applied force, the impetus imparted to the counter wheel receiving its motion through the agency of the transferring mechanismv might at times be sufficient to move said wheel a distance of two ratchet-teeth, whereas a movement the distance of only one tooth is necessary. I prevent this by arranging a transverse plate 40 approximately tangent to the periphery of the counter-wheels, so that the pin 38 upon the pawl 37 after advancing the counter-wheel the distance of a single ratchet-tooth is jammed between the plate 40 and the face of the nearest ratchettooth, after which it is returned to its eriginal position to engage the next tooth upon the counter-wheel. To permit line adjust ment of the plate 40, the same is mounted upon the end of an adjustable rod 4l, adjusted by means of a nut 42 on the interior of the case.

The operation of the registering mechanism is as follows: We will assume the amount of a sale to be nine dollars and fifty-two cents. The operator will rst engage the ninth linger upon the operating-plate 22, adapted for registering dollars, and press the same down with his finger, which will contact with the ledge on the ease, which serves as a stop. The plate 22 and the fingers thereon when depressed will be in the position c in dotted lines, Fig. 3. The operator removing his finger, the plate 22 will instantly return te its normal position because of the spring 29 and the intervening connections. in like manner the fifth linger on the middle or dimes plate is engaged to depress the same and also the cents-plate. The counter-wheel for registering cents will consequently advance the distance of two ratchet-teeth or two numbers, the counter-wheel for registering dimes ve numbers, and the counter-wheel for registering dollars nine numbers. The total amount of cash sales may be read from the forward side 4of the counter-wheels, as 49, 90, 9, indicating total cash sales of forty-nine dollars and ninety-nine cents, the hinged closure '7 being unlocked when it is desired to read ,the numerals upon the counter-wheels. To facilitate the reading of the numerals upon the counter-wheels, a plate having three rectangular perforations in alinement with the numerals may be provided immediately forward of the counter-wheels.

Iwill now describe the indicating mechanism which l employ in connection with my registering mechanism. The band-wheels 2G, hereinbefore mentioned, are independently rotatable upon concentric shafts 43, 44, and.

45, respectively. (Shown in section in Fig. l0.) At the opposite ends of the shafts 43, 44, and 45 are keyed or otherwise secured cylindrical band-wheels 46, 47, and 4S, respectively. By the arrangement disclosed the band-wheel 4S will move simultaneously with the band-wheel 2U at the eXtreme left, the wheel 47 with the middle wheel 26, and the wheel 46 with the adjacent wheel 2G.

40 and 50, respectively, are indicator-CyL inders to indicate the number of cents registered upon the machine, the same being keyed or otherwise secured upon the extreme ends of a shaft 5l.

52 and 53 in like manner are cylinders to indicate the number of dimes registered, the same being mounted to rotate simultaneously upon a tubular shaft 54, concentric to shaft 5l.

55 is a cylinder to indicate the number of dollars registered. The same is made of greater width than the other indicator-cylinders referred to, so as to accommodate two rows of numerals, and is keyed or otherwise secured to a tubular shaft 5G, concentric to shafts 5l and 54. Cylinders 50, 53, and 55 are each provided with a winding-drum 57, to the peripheries of which are secured the ends of operating-cords 58, of silk or other suitable material to insure flexibility. Cords 5S after being secured to the drums 57 are given one or a number of turns about the same, as shown, to cause the indicator-cylinders to rotate in the direction of the arrow, Fig. 4, when the operating-cords are unwound from the drums. The opposite ends of the cords are secured to the peripheries of the wheels 4G, 47, and 4S, the cord from cylinder 50 connecting with band-wheel 46 and those from cylinders 53 and 55 with band-wheels 47 and 4S, respectively. The normal positions of the indicator-cylinders are shown in Fig. 2, to which the same are returned after being released :from their indicating positions by a band-spring 59, the outer terminals of which are secured to a transverse rod GO and the inner ends to shafts 5l, 54, and 5G, respectively. Each cf the cylinders 50, and 55 is provided with a peripheral projection in the form of a pin Gl, which serves as a stop to arrest the motion of the cylinders upon the return to their normal positions. Suitably connected with the cylinders 50, 53, and 55, so as to operate simultaneously therewith, are ratchet-disks 62, provided with peripheral ratehet-teeth- The ratchet-teeth correspond in number to the numeralsspaces upon the face of each iudicatorcylinder. The cylinders on either end te indicate cents are provided on their faces with numerals correspending with those upon the cents-operating plate-to wit, 2, 3, 4, 5, 6, 7, 8, 9-and a blank space. The cylinders for indicating dimes are in like manner provided with numerals corresponding with those upon the dimes-operatingplateandablankspaceA The cylinder ,for indicating dollars is provided IOO IIO

with two rows ot' numerals corresponding to the numerals upon the dollars -indicating plate, the usual blank spaces also being provided thereon. 63 represents similar levers, loosely pivoted at 64 and having laterallyextending arms 65 integral therewith. Projecting laterally from the arms 65 are pins 66, adapted to engage the teeth upon the ratchetdisks 62. The same are, however, normally disengaged from the teeth of said disks, the arms 65 being acted upon by gravity, taking the position in dotted lines, Fig. 4. Near the lower ends of levers 63 are provided eyes 67, adapted to encircle the operating-cords 58.

68 is an upwardly-extending arm rigidly secured in any suitable manner to the drawerreleasing key-lever 4, assuming the position in dotted lines, Fig. 4, when the key-lever 4 is depressed to open the cash-drawer. Arm 68 is formed with branches 69, adapted to contact with the levers 63 near their lower ends to disengage the pins 66 from the teeth ofthe ratchet-disks 62.

The operation of the indicating mechanism is as follows: The cents, dimes, or dollars operating plates being depressed, the band-Wheels 26 will rotate to cause the bandwheels 46, 47, and 48 to also rotate in the direction ofthe arrow, Fig. 4. The operating-cords 58 will consequently be wound upon the band- Wheels 46, 47, and 48, the same unwinding from the drums upon the indicator-cylinders to rotate the same in the direction of the arrow. The operating-cords 58 are normally snfliciently slack to permit the levers 63 to assume the normal positions in dotted lines, Fig. 4, the pin 66 also being disengaged from the ratchet-disk 62. However,when the cords 58 are under tension to operate the indicatorcylinders the levers 63, the arms 65, and the pins 66 will be moved to the position in full lines, Fig. 4, to engage the disks 62 to hold the indicator-cylinders at their proper indicating-points. When the operating-plates 22 of the registering mechanism are released, the wheels 46, 47, and 48 will return to their normal positions and unwind the operatingcords 58, the same hanging loosely, as shown in dotted lines, Fig. 4, the indicator-cylinders remaining in their indicating positions, because of engagement of the pins 66 with the teeth of the ratchet-disks 62. The indicatorcylinders will remain in indicating position until the key-lever 4 is depressed to release the cash-drawer, the arm G8, being rigidly connected with the key-lever, assuming the position in dotted lines, Fig. 4, and by contact with the arm 68 releasing the indicatorcylinders, which will resume their normal positions because of the springs 59. The indicator-cylinders arranged as shown will indicate from both the front and the rear of the register, the openings 9 in the case being provided at both the front and the rear in line with the numerals upon the indicator-cylinders. The positions of the openings 9 are shown by the dotted circles, Fig. 2. To provent access to the indicator-cylinders, the openings are provided with a glass plate to permit the indicatornumerals to be read therethrough. I may also employ magnifying-lenses to be placed in the openings 9 to magnify the indicator-nuinerals.

A brief statement of the operation of the register is as follows: The key-lever 4 is depressed to open the cash-drawer, the operation releasing the indicatorcylinders, the same then showing' blank spaces through the openings 9. The cash-drawer is then closed and the amount of a sale registered by depressing the operating-plates. The amount ot the sale will then be indicated by the numerals upon the indicating-wheels, the same appearing through the openings 9.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
